MDMP System

Introduction:

MDMP stands for Multi Display, Multi Processing.

A Multi-Display, Multi-Processing code pages system (MDMP system) uses more than a single code page on the application server. Depending on the login language, it is possible to switch dynamically between the installed code pages. MDMP therefore provides a vehicle for using languages from different code pages in a single system.

MDMP was the solution SAP developed for support of combinations of multiple code pages in one system prior to the availability of unicode database support. MDMP effectively enabled an SAP ERP system to be installed with a non-unicode database, and to support connections to the ERP application by users with language combinations not supported by a single code page.

Example: support of one ERP system with English, French, Japanese, and Chinese.

MDMP implementations implemented strict rules and restrictions in order to ensure data consistency and avoid data corruption.

MDMP was only supported for SAP R/3, SAP R/3 Enterprise, and mySAP ERP applications.

No other SAP applications or SAP NetWeaver components support MDMP.

Future of MDMP:

MDMP was a short term solution delivered to customers until unicode was released for SAP ERP applications. Once unicode was released, MDMP was not recommended to customers. Therefore SAP strongly recommends utilizing unicode versions of SAP ERP for multi-language solutions that require multiple codepages.

Note: Unicode is supported from SAP R/3 Enterprise onwards

For those ERP customers already running MDMP, SAP has clarified the ongoing support of MDMP in a letter to customers:

MDMP will no longer be fully supported from mySAP ERP 2005 onwards:

From mySAP ERP 2005 onwards SAP can only warrant for consistent data in installations with mixed languages (more than one code page) if the whole system is based on Unicode.

In cases where customers want to use MDMP from mySAP ERP 2005 onwards, SAP strongly recommends involving an experienced SAP consultant, but SAP disclaims all responsibility for

any damages or losses of (productive) data and Interruption of or restrictions for scenarios in mixed environments (E.g. Unicode <-> MDMP - systems) unless such damages are attributable to SAP’s willful misconduct or gross negligence.

Conversion from MDMP to Unicode:

SAP provides migration tools and services to support the conversion of non-unicode and MDMP systems to unicode.

SAP has announced that as of 2007, there will no longer be shipments of non-unicode installation kits for new releases of applications that run on SAP NetWeaver or SAP NetWeaver itself.
